  • Patent number: 4112847
    Abstract: A warhead with a disintegrating jacket to house several projectiles, in picular splinter projectiles. The projectiles are each equipped with an ignition and backfiring system and fall to earth individually after disintegration of the warhead jacket. They are then fired upwards by means of the backfiring charge ignited by the ignition system, the charge explosive then being detonated. The ignition system of each projectile consists of a time-delay fuze and an impact fuze. The time-delay fuze is initiated when the projectile impacts with relatively soft ground and ignites the backfiring charge after adjusted times differing at least partly for the individual projectiles. The impact fuze, however, effects an immediate ignition of the backfiring charge when the projectile strikes relatively hard ground.

  • Patent number: 4111126
    Abstract: A warhead for use against armored targets, comprising a shaped charge and aftereffect caused by a second annular explosive charge located in front of the shaped charge, with the explosive charge arranged at the base of a hollow body (nozzle) tapered in target direction. A funnel-shaped sleeve is disposed between the shaped charge and the second explosive charge, and detonation transmission elements are arranged on its outer circumference. The jet from the shaped charge passes the second explosive charge prior to the latter's detonation. Behind the hole produced by the shaped charge jet an aftereffect takes place which is caused by the active mass flow accelerated in axial direction by the second explosive charge.

  • Patent number: 4051763
    Abstract: A protective armament or intercept system includes a plurality of explosive harges arranged in a grid pattern in spaced parallel relationship to a grid sensing pattern formed by intersecting light sources each of which are aimed at respective photoelectric cells. The light sources and the photoelectric cells form a protective and sensing field with intersecting points which are in alignment with respective explosive charges and when the light sources at an intersecting point are broken, the receiving photoelectric cells for the broken light sources will be influenced so as to ignite the charge which is in alignment with the broken intersection point of the light sources. The construction of a preferred explosive charge and the various preferred arrangements of the explosive charges in respect to the sensing pattern formed by the photoelectric cells and light sources are set forth and described in respect to the protection of an aircraft hanger and a movable vehicle such as a tank by way of example.

  • Patent number: 3974771
    Abstract: A splinter warhead for guiding flying bodies for combating aerial targets by detonation by a proximity fuse upon close approach to the target includes front and rear body portions interconnected by a warhead envelope constructed as a splinter warhead transporting structural member carrying an explosive charge detonatable by the proximity fuse. The explosive charge, which has an essentially circular cross section, has a lining of pre-formed splinters on its peripheral surface, this lining being disposed between the explosive charge and the warhead envelope. The pre-formed splinters have essentially a ball or spherical shape and an individual weight of less than 1 g. The average diameter of the explosive charge is more than 25 times the average diameter of the splinters. The splinters may be arranged in a single layer or in more than one layer, and may be all of the same diameter, or the splinters may be of different diameters and be arranged in groups with each group comprising splinters of the same diameter.
